What Is a Blank Sim Card?
A blank SIM card is a SIM card that is free of information. Typically, users who express interest in purchasing a blank SIM card do so for practical reasons. Blank SIM cards allow users to change phone numbers, back up information or clone existing SIM cards for dual service
Using a blank SIM card generally means that a user is given a digital clean slate. Since there is no information on a blank SIM card, users have to re-enter contacts and other associated cell phone account details onto the SIM card. Different phone numbers are usually associated with the new cards. A blank
SIM card is also commonly given to users who request a replacement SIM card due to the destruction or loss of a previous SIM card.
Blank SIM cards may also be purchased by users who simply want a way to back up the information contained on their existing SIM cards. Cell phone owners may use SIM card readers, writers and editors to help transfer the information over to the new SIM card, modify information and enter new details onto the card. The same contacts, text messages and other associated SIM card information can then exist on the two SIM cards.
Others users may desire a blank SIM card for cloning purposes. During cloning, the blank SIM card is configured to serve as a complete duplicate of another SIM card. The information on the two SIM cards, including the phone number, are the same. After the process is completed, users may be able to use the blank SIM to place calls and have the charges attributed to the original SIM card. The practice of cloning is illegal and blank SIM cards should not be obtained for this purpose.
Blank SIM cards are typically inexpensive. They usually accompany new cell phones to aid in the proper activation of a new phone line. However, a new phone line is not required to obtain a blank SIM card. They may be easily purchased from cell phone company websites.
Users who wish to purchase blank SIM cards should keep an important point in mind: not all SIM cards will work with every phone. Users should verify that the SIM card works with their cell phones and carriers before purchasing it. Should a user buy a SIM card that isn't compatible, the SIM card will be useless and his or her money will be wasted.
